Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies within Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...
"Final report to the U.S. Environmental Protection Agency. Funds supporting this study have been provided by Region 10 of the U.S. Environmental Protection Agency, Seattle, WA."
Dover sole (Microstomus pacificus) has been subject to intensive fishing In waters off northern Oregon-southern Washington (specifically PMFC Area 20) since 1941 (Harry, 1956). This species has always been an Important contributor to the trawl fishery and has been the most valuable species of groundflsh landed In Oregon since 1966....
A technique is presented to remotely measure the scales and morphology of natural sandbars based
on the preferential dissipation of wind waves and swell over the crests of the bar. Photographic or
video images are recorded and statistical uncertainties associated with incident wave height modulations
removed by averaging (time exposures)....
We present an optical method (optical current meter) to measure the longshore
component of nearshore surface currents by measuring the alongshore drift of persistent
sea foam in the surf zone. The method uses short time series of video data collected from
an alongshore array of pixels. These space-time data are...
